FEED-OPERATING MECHANISM.

Specification of Letters Patent.

Patented March 26, 1907.

Application filed May 1, 1905. Serial No. 253,903.

To cwZ whom it may concern.-

Be it known that I, HARRY L. JEFFRIES, a citizen of thejUnited States of America, and a resident of Grimes, Polk county, Iowa, have inventeda new and usefulFeed-Operating Mechanism, of which the following is a specification.

My object is to combine a lubricator with an engine in such a manner that the operating-lever can be readily adjusted relative to a plunger in a pump-cylinder and a standard connected with the valve-stem of the engine as required to regulate the feeding of the oil to the engine advantageously in very materially diil'erent quantities at different times.

My invention consists in the construction, arrangement, and combination of operative mechanism with an engine and an oil-cup, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 is a plan illustrating the application of my improved device to a steam-cylinder and valve-stem. Fig. 2 is an elevation of the mechanism shown in plan in Fig. 1. Fig. 3 is an elevation, partly in section, illustrating the construction of parts of my improved device.

In the construction of the mechanism and its mounting, as shown, the numeral 10 designates the steam-chest, 11, the steam-supply pipe, 12, the valve-stem operating the valve in the steam-chest, and 13 the cylinder of a slide-valve engine of common or conventional form.

A pump stock or cylinder 14 is provided and is formed with a base 15, adapted to be mounted rigidly on the steam-chest 10. A T 16 is formed on the end portion of the cylinder 14 adjacent the supply-pipe 11, and pipes 17 18 communicate with and lead or extend laterally from said T. The pipe 17 is provided-with an ingress check-valve of conventional form in a chamber 19, and a receptacle or cup 20, adapted to contain a supply of lubricant, such as soft oil, is mounted on and communicates with the outer end of said pipe. The oil-cup 20 is provided with a stop-valve of conventional form in a chamber 21. The pipe 18 extends beyond a chamber 22, containing an egress check-valve, and enters the steamsupply pipe 11. At the entrance of the pipe 18 to the steam-supply pipe 11 another egress check-valve is located in a chamber 23, the function of the egress check-valves being to prevent the steam gm the pipe forcing the lubricant backward. A solidjpiston or plunger 24 is mounted in and extends outside of the cylinder 14, and a stuiiing-box 25, of conventional form, surrounds and packs said piston at the entrance to the cylinder. A fulcrum 26 is mounted for oscillation on the base 15 of the cylinder 14, and a lever 27 is pivoted at its lower end on and rises from said fulcriun. The lever 27 is pivotally connected intermediate of its ends to the outer end portion of the piston or plunger 24. A standard 28 is fixed to, and rises from the valve-stem l2, and a rod 29 connects said standard to the lever 27. One end portion of the rod 29 is pivoted to the standard 28 by a bolt 30, extending through a hole in the rod and through one or another of holes 31 in the standard, and the opposite end portion of said rod is pivoted to the lever 27 by a bolt 32, extending through a hole in the rod and through one or another of holes 33 in the lever. 'lhe bolt 30 may be adjusted into either of the holes 31 in the standard, and the bolt 32 may be adjusted into either of the holes 33 in the lever to adjust the movement of the lever, and consequently of the piston or plunger 24, relative to the movement of the valve-stem 12.

In the practical use of this device the flow of lubricant is established and maintained only during the operation of the engine, since said flow is dependent wholly on a movement of the valve-stem 12. When the valvestem 12 is reciprocated, as by the operation of the engine, such movement is transmitted through the standard 28, rod 29, and lever 27 to the piston or plunger 24. In its forward movement the plunger or piston 24 forces oil out of the cylinder 14 and pipe 18 into the steam-supply pipe 11, where said oil mingles with the steam entering the steamchest and cylinder 13 and lubricates the slide-valve and engine-piston. In its rearward movement the piston or plunger 24 sucks a supply of oil into the pipe 17 and cylinder 14 from the receptacle or oil-cup 20, and the check-valve in the chamber 19 prevents return of said oil to the receptacle.

It is obvious that by adjusting the link 29 on the lever 27 and also on the standard 28 the motion of the plunger 24 in the cylinder can be very minutely and advantageously governed for regulating the feeding of oil to the engine.

I claim as my inventionand adj ustably connected with the standard 16 A feed-operating mechanism comprising a and the lever, arranged and combined to opfulcrum pivoted to the base of a cylinder, a erate in the manner set forth.
